1.It is possible to use the method by avoiding the difficulties of accurately measuring the target velocity V_m and its azimuth η_m.
该方法避开了在应用平行接近法时需要精确量测目标速度V_m和目标运动方位角η_(?) 的难题,使得平行接近法的应用成为可能.收藏指正
2.radar that will report altitude as well as azimuth and distance of a target.
能够测定目标的高度方位和距离的雷达。收藏指正
3.The azimuth from the launch point to the target was about 346 deg., or 15 deg. west of due north.
有关消息来源称，发射点至目标的方位角约346度，或者说北偏西15度。收藏指正
4.A method of accurate measurement of the range,azimuth and elevation of a target is developed under the background of strong interference for sparse array synthetic impulse and aperture radar (SIAR). Computer simulation results show this method is effective.
本文在第一部分的基础上进一步介绍稀布阵综合脉冲孔径雷达（SIAR）在强干扰背景下对目标的距离、方位和仰角进行精确测量与跟踪的方法，通过计算机模拟证明了该方法的有效性。收藏指正
5.Because of the vertical displacement,lateral displacement and longitudinal displacement of the ship,as well as the line displacement of the sonar array caused by ship rocking,the azimuth and angle of pitch between the sonar array and the target do not immobilize.
由于船舶垂向位移、横向位移和纵向位移,以及船舶摇摆引起的声纳基阵的线位移,声纳基阵相对于目标的方位角和俯仰角不是固定不变的。收藏指正
6.This paper derives the effective synthetic aperture length equation expressed as the initial position, the velocity and the synthetic aperture time when the radar operates in spotlight mode and the vehicle does uniform straight line motion, gives the ideal azimuth resolution equation expressed as the radar wavelength, the angles between velocity vector and line of sight from the antenna phase center to target at the begining and end time of synthetic aperture.
